Arianespace to launch GEO-KOMPSAT 2A and 2B satellites for Korea Aerospace Research Institute

The Korea Aerospace Research Institute (KARI) has chosen Arianespace to launch the two satellites in its GEO-KOMPSAT-2 program. Mr. Jacques Breton, Senior Vice President, Sales & Customers of Arianespace and Mr. CHO Gwangrae, President of KARI, have signed today the launch contract for GEOKOMPSAT-2A & -2B.

GEO-KOMPSAT-2A (GK2A) and GEO-KOMPSAT-2B (GK2B) will be orbited by Ariane 5 launchers in May 2018 and March 2019 from the Guiana Space Center, Europe’s Spaceport in Kourou, French Guiana.

For nearly 25 years now, Arianespace and KOREA’s satellite technology research centers have developed a sound relationship, with the launch of both scientific microsatellites and the COMS multi-mission satellite. GEO-KOMPSAT-2A (GK2A) and GEO-KOMPSAT-2B (GK2B) will be the seventh and eighth satellites launched by Arianespace for South Korea.

Each of the GEO-KOMPSAT-2 satellites will weigh about 3,500 kg. at launch, and will be positioned in geostationary orbit at 128.2° East.

The satellites will be built by KARI at its facility in Daejeon, South Korea. The two governmental GEO-KOMPSAT-2 satellites will primarily perform meteorological observation and space weather monitoring (GK2A), and ocean and Earth environmental monitoring (GK2B).

Arianespace Chairman and CEO Stéphane Israël welcomed the contract signing, saying: “Arianespace is extremely proud of its selection by the Korean space agency, KARI. Our last launch for KARI occurred in 2010. Now, we have been chosen again by KARI to launch these two impressive meteorological observation missions. Contributing to Korean space achievements is a great honor for Arianespace. I would once again like to thank the Korea Aerospace Research Institute for selecting us. Arianespace will deliver.”

And, from Arianespace edges out SpaceX to launch Korean satellites, by Stephen Clark, dated February 16, 2015:

Korean officials weighed bids from Arianespace and SpaceX to launch the satellites, but ultimately selected the French launch provider for the job, according to a statement by South Korea’s Ministry of Science, ICT and Future Planning.

While noting that SpaceX’s arrival on the market has “revolutionized” the commercial launch business, the ministry’s statement singled out the Ariane 5 rocket’s long record of success — 47 straight successful launches for its Ariane 5 ECA rocket variant — as a strong point in a discussion of the government’s decision.

Responding to SpaceX’s prices for its Falcon 9 rocket, Arianespace has instituted a discount for smaller satellites properly sized to ride in the lower position in the Ariane 5 launcher’s dual-payload fairing.

And, from ITT Exelis, Ball Win S. Korean Environmental Sensor Contracts, by Warren Ferster, dated April 10, 2013:

Two U.S. companies, ITT Exelis and Ball Aerospace & Technologies Corp., have beaten out European competitors to provide environmental monitoring sensors for a pair of South Korean multipurpose satellites slated to launch in 2017 and 2018.

The Geo-Kompsat 2A and 2B satellites will carry a combined payload including communications transponders and environmental sensors.

Exelis of Rochester, N.Y., will supply a variant of its Advanced Baseline Imager for Geo-Kompsat 2A , scheduled for a 2017 launch, under a multimillion-dollar contract, the company said in an April 8 press release. The Advanced Baseline Imager (ABI) is the primary sensor for the U.S. government’s next-generation Geostationary Operational Environmental Satellite (GOES)-R program, whose first launch is slated for 2015.

The first flight-model ABI is in thermal vacuum testing, said Christopher D. Young, president of Exelis Geospatial Systems.

Both Ball and Exelis beat out competing bids from divisions of Europe’s Astrium space hardware and services company, according to industry officials.

I was wondering what that Seoul-Edmonton-Cayenne flight was carrying.

GSAT-11 returns to Guiana for December launch

Quote
GSAT-11, the heaviest Indian communication satellite built to date, for faster Internet connectivity, is back once again at the Guiana Space Centre for an early December launch. K. Sivan, Chairman of the Indian Space Research Organisation (ISRO) and Secretary, Department of Space, confirmed on Wednesday that the 5,700 kg spacecraft was shipped out of Bengaluru last week and has reached the European launch port.

GSAT-11 is built to provide the Indian region superior communication and 12 GBPS connectivity with its multiple spot beams in Ka and Ku bands.

ISRO Chairman has announced that GSAT-11 will be launched on December 4 from French Guiana.

Quote
The chairman said India's heaviest satellite Gsat-11 weighing over 5.7 tonnes, which was earlier recalled from French Guiana to check for any possible anomalies, "will now be launched from the European spaceport on December 4". Gsat-11 is also a high throughput communication satellite that will help usher in high-speed internet era in the country.
